The treatment of urothelial carcinoma (UC) had remained unchanged for several years until the recent FDA approval of immune checkpoint inhibitors (CPIs) in the salvage setting. Novel dual CPI-CPI and CPI-chemotherapy combinations are now being investigated aggressively as first line therapy for metastatic disease. Areas Covered: We discuss the recent insights into the tumor biology of UC, which may impact the prognosis as well as assist in developing precision medicine. This is followed by an overview of existing treatment including conventional chemotherapy as well as the trials that led to the recent approval of PD-1 and PD-L1 inhibitors...

Lung cancer treatment has considerably changed over the last few years: the identification of druggable oncogenic alterations and innovative immunotherapic approaches granted lung cancer patients the possibility of more efficient and less toxic therapeutic options than chemotherapy. Nowadays, lung squamous cell carcinomas (SqCCs) patients have the chance to benefit from novel treatment alternatives, including immune checkpoint blockade and anti-angiogenic agents and, given positive trial results, from afatinib, a second generation tyrosine kinase inhibitor (TKI) that irreversibly antagonizes ErbB family tyrosine kinase receptors...

The cure rate of osteosarcoma has not improved in the past 30 years. The new treatments and drugs is urgently needed, especially for metastatic osteosarcoma. Anti-angiogenesis therapy and immunotherapy has got promising anti-tumor effects in various tumors. It is hypothesised that combining checkpoint inhibitor immunotherapies with antiangiogenic treatment may have a synergistic effect and enhance the efficacy of both treatments. However, its underlying mechanism remain largely uninvestigated. To investigate the clinical significance of vascular endothelial growth factor receptor-2 (VEGFR2) and programmed death ligand-1 (PD-L1) in osteosarcoma, we analyzes their expression levels in 93 osteosarcoma specimens by immunohistochemistry...

Immune checkpoint inhibitors have gained traction over the last few years in the treatment of metastatic/recurrent head and neck squamous cell carcinoma (HNSCC) patients. Monoclonal antibodies that block the programmed death 1 (PD-1) receptor and its major ligand, PD-L1, have shown durable responses and low toxicity profiles. There are currently no validated predictive biomarkers to select patients likely to respond to anti-PD-1/PD-L1 therapy to avoid unwanted side effects and to reduce healthcare expenditure...

Introduction Due to enhanced T-cell activity, immune checkpoint inhibitors cause immune-related adverse effects. Corticosteroids are the mainstay of immune-related adverse effect management but the optimal strategy has not been determined, putting patients at risk for steroid-related adverse effects and potentially decreased efficacy of immunotherapy. This study aims to characterize the use of corticosteroids for the management of immune-related adverse effect. Methods and materials A retrospective, single-center evaluation of patients receiving checkpoint inhibitors was conducted...

Immunoglobulin (Ig) G1 antibodies stimulate antibody-dependent cell-mediated cytotoxicity (ADCC). Cetuximab, an IgG1 isotype monoclonal antibody, is a standard-of-care treatment for locally advanced and recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN) and metastatic colorectal cancer (CRC). Here we review evidence regarding the clinical relevance of cetuximab-mediated ADCC and other immune functions and provide a biological rationale concerning why this property positions cetuximab as an ideal partner for immune checkpoint inhibitors (ICIs) and other emerging immunotherapies...

Non-Hodgkin lymphoma is a malignancy of B lymphocytes that typically infiltrate sites of disease, including the lymph nodes, spleen, and bone marrow. Beyond the presence of malignant cells, many immune cells are also present within the tumor microenvironment. Although these immune cells have the potential to regulate the growth of malignant B cells, intratumoral immune cells are unable to eradicate lymphoma cells and most patients with lymphoma have clinical evidence of disease progression. Recent data have identified some of the mechanisms that account for the suppressed antitumor immune response and have created opportunities for treatment to overcome the deficiencies...

Primary mediastinal B-cell lymphoma (PMBCL) is recognized as a distinct clinicopathologic entity that predominantly affects adolescents and young adults and is more common in female subjects. Although PMBCL is considered to be a subtype of diffuse large B-cell lymphoma, its clinical, morphologic, and biological characteristics overlap significantly with those of nodular sclerosing Hodgkin lymphoma (NSHL). Over the past few years, the shared biology of these 2 entities has been highlighted in several studies, and mediastinal gray zone lymphoma, with features intermediate between PMBCL and NSHL, has been recognized as a unique molecular entity...

Context: Immune checkpoint inhibitors, including anti-PD-1, anti-PD-L1 and anti-CTLA4 monoclonal antibodies, have been widely used in cancer treatment. They are known to cause immune-related adverse events (irAEs), which resemble autoimmune diseases. Anterior pituitary hypophysitis with secondary hypopituitarism is a frequently reported irAE, especially in patients receiving anti-CTLA4 treatment. In contrast, posterior pituitary involvement, such as central diabetes insipidus (DI), is relatively rare and is unreported in patients undergoing PD-1/PD-L1 blockade...

Soft tissue and bone sarcomas are malignancies of mesenchymal origin, and more than 50 subtypes are defined. For most sarcomas, locally advanced or unresectable disease is still treated with cytotoxic chemotherapy. Recently, our understanding of subtype-specific cancer biology has expanded, and it has revealed distinct molecular alterations responsible for tumor initiation and progression. These findings have motivated the development of targeted therapies that are being evaluated in subtype-specific or biomarker-driven clinical trials...

Immunotherapy has become a promising alternative therapeutic approach for cancer patients. Interruption of immune checkpoints, such as CTLA-4 and PD-1, has been verified to be a successful means for cancer therapy in clinical trials. Monoclonal antibody (mAb) targeting to PD-L1 has been approved to treat urothelial carcinoma, non-small cell lung cancer or merkel cell carcinoma by the Food and Drug Administration (FDA). However, the high cost of the antibody can limit its application. In our study, TPP-1 (targeting PD-L1 peptide), which specifically binds to PD-L1 with high affinity, was identified through bacterial surface display methods...

CD8+ T cell-dependent killing of cancer cells requires efficient presentation of tumor antigens by human leukocyte antigen class I (HLA-I) molecules. However, the extent to which patient-specific HLA-I genotype influences response to anti-PD-1 or anti-CTLA-4 is currently unknown. We determined the HLA-I genotype of 1,535 advanced cancer patients treated with immune checkpoint blockade (ICB). Maximal heterozygosity at HLA-I loci (A, B, and C) improved overall survival after ICB compared to patients who were homozygous for at least one HLA locus...

PURPOSE: T cells infiltrating follicular lymphoma (FL) tumors are considered dysfunctional, yet the optimal target for immune checkpoint blockade is unknown. Characterizing co-inhibitory receptor expression patterns and signaling responses in FL T-cell subsets might reveal new therapeutic targets. EXPERIMENTAL DESIGN: Surface expression of 9 co-inhibitory receptors governing T-cell function was characterized in T-cell subsets from FL lymph node tumors and from healthy donor tonsils and peripheral blood samples, using high-dimensional flow cytometry...

Merkel cell carcinoma (MCC) is a rare (~2,000 US cases/year) but aggressive neuroendocrine tumor of the skin. For advanced MCC, cytotoxic chemotherapy only infrequently (<10% of cases) offers durable clinical responses (>1 year) suggesting a great need for improved therapeutic options. In 2008, the Merkel cell polyomavirus (MCPyV) was discovered and is clonally integrated in ~80% of MCC tumors. The remaining 20% of MCC tumors have large numbers of UV-associated mutations. Importantly, both the UV-induced-neoantigens in virus-negative tumors and the MCPyV T antigen oncogenes that are required for virus-positive tumor growth are immunogenic...

The mitogen-activated protein kinase (MAPK) pathway is intimately implicated in the molecular pathogenesis of non-small-cell lung cancer (NSCLC). Aberrant MAPK signaling resulting from the upstream activating mutations converges on mitogen-activated protein kinase kinase 1/2 (MEK1/2), making MEK inhibition an attractive strategy for the treatment of NSCLC. Several MEK inhibitors have demonstrated anticancer activity in patients with NSCLC. Areas covered: In this article, we discuss the biological rationale for the use of MEK inhibitors and summarize the clinical experience with MEK1/2 inhibitors for the treatment of NSCLC, from initial phase I studies to phase II/III studies, both as monotherapy or in combination with other anticancer agents...

The blockade of PD-1/PD-L1 interaction by peptide antagonists can unleash and enhance pre-existing anti-cancer immune responses of T cells to eradicate cancer cells. However, low proteolytic stability is the "Achilles' Heel" of peptides. Here, we first report a nanoantagonist with a physiological temperature sensitive nanophase-segregated surface that exhibits significantly enhanced blood circulation, peptide stability and PD-L1 immune checkpoint blockade efficacy. Thermosensitive polymers with different phase transition temperatures (Tt) are used to form the nanophase-segregated surface on an Au nanorod core...

The immune system interacts closely with tumors during the disease development and progression to metastasis. The complex communication between the immune system and the tumor cells can prevent or promote tumor growth. New therapeutic approaches harnessing protective immunological mechanisms have recently shown very promising results. This is performed by blocking inhibitory signals or by activating immunological effector cells directly. Immune checkpoint blockade with monoclonal antibodies directed against the inhibitory immune receptors CTLA-4 and PD-1 has emerged as a successful treatment approach for patients with advanced melanoma...
